There’s nothing the internet enjoys more than spectacularly foolish accidents where nobody gets hurt, so we can all joke about how dumb people are with a clear conscience.

Take this video circulating on Reddit today, of construction workers in Oregon digging a trench without properly reinforcing the walls. An OSHA employee arrives at the site to find a man down in the trench, with a heavy mass of dirt just waiting to fall on his head.

“Looks like you’ve got a bit of a shoring problem going on,” the official says. “He can’t be down there. How are you going to get him out?”

The other workers start to argue – and as if on cue, the dirt crumbles and the worker in the trench has to leap onto a pipe to keep from being buried, proving the exasperated official’s point. “You wanted to see why he can’t be down there? That’s why he can’t be down there.”
